Obstructive Hypopnea

Definition - What does Obstructive Hypopnea mean?

Obstructive hypopnea is a medical condition characterized by partial blockage of the airway as soft tissue musculature lining the back of the throat relaxes or collapses, slowing or occluding normal breathing patterns, depending on its severity. Hypopnea is often a concurrent factor of obstructive sleep apnea hypopnea syndrome (OSAHS), influencing respiratory rate to the extent that blood oxygen levels can decline leading to cardiovascular issues or cognitive dysfunction. With obstructive hypopnea, many people can experience sporadic episodes of irregular breathing that can disrupt biorhythms, undermining the quality of life at home and work.

WorkplaceTesting explains Obstructive Hypopnea

The Apnea-Hypopnea Index (AHI) is the medical criterion for measuring the cumulative number of hypopnea spells occurring per hour to determine the proper treatment method. A doctor will account for symptoms including snoring, erratic mood, chronic fatigue, excessive daytime sleepiness, and insomnia, contributing to the frequency and duration of obstructive hypopnea disturbances. Therapeutic modalities can help normalize circadian rhythm cycles during the night by providing steady airflow at a pressure consistent with the physiological needs of its subject. For instance, continuous positive airway pressure (CPAP) devices can be applied for patients with hypopnea or sleep apnea issues, facilitating the process of autonomous oxygen uptake in the lungs.

Due to its link with obesity and smoking, obstructive hypopnea carries significant epidemiological health risks as individuals are more susceptible to heart disease or stroke. Early detection of obstructive hypopnea can dictate the course of regular sleep patterns, limiting or preventing ongoing fatigue and daytime sleepiness that can affect job performance. According to the National Sleep Foundation, hypopnea and sleep apnea episodes interrupt rapid eye movement (REM) deep sleep cycles responsible for assimilating, processing, and storing information coupled with keeping motor reflexes intact.

Since OSAHS-related cases can interfere directly with REM sleep, employers who conduct obstructive sleep apnea (OSA) and affiliated testing can benefit from helping applicants and employees receive proper treatment. A proactive approach can reduce occupational hazards connected with hypopnea/sleep apnea, in particular, positions that require handling heavy machinery or operating a commercial vehicle. While many people might attribute symptoms to stress or family obligations, obstructive hypopnea can point to an underlying health condition that compromises longevity of life.
